Dometic is a massive brand with products that are leading the way in the global market. Manufacturers and solution providers for people using recreational vehicles are their primary focus. There are a wide variety of products available, ranging from applications for everyday use to safety and security.

The company also offers boats, trucks, RVs, and even cars. Dometic offers a wide range of toilets that are designed exclusively for RVs because they keep this in mind . The Dometic 310 toilets are full-sized, lightweight, and have a simple design. This makes it one of the best options when selecting a toilet for RVs. These toilets are surprisingly powerful even though they are very lightweight.

The Dometic 310 is a gravity discharge toilet and it performs much better than other toilets of a similar category due to an added feature, a slow close seat cover. It makes this toilet very easy to use, more comfortable, and long-lasting. This toilet has an excellent ‘power flush’ system that flushes the whole toilet with only 0.4 liters of water.

The pedal flush system is also an improved and important feature of this model. The pedal is designed for one side push. The user slightly pushes the pedal down to fill the water to the bowl (if required) and then presses it down completely to flush.

These features make Dometic 310 toilets among the most popular toilets, especially for RVs. Despite constant improvements, these toilets remain durable. The Dometic 310 toilet may, however, cause some people to experience some problems. The purpose of this article is to describe some of the problems you might encounter and how to deal with them.

Common Dometic 310 Toilet Problems

1. Pedal Not Working

Pedal Not Working

Dometic toilets don’t have a traditional flushing system that uses a button present on the top of the back tank. Instead, Dometic 310 toilets have a toilet pedal either present in front or on the side of the toilet. When you push this pedal the toilet is flushed. Some Dometic toilet models like Dometic 310 have pedals placed on the side.

These pedals are one of the easiest and best ways of flushing the commode after use. You don’t need to stand up or turn around to push the button or pull the lever at the top of the tank to flush the toilet. You even can flush the Dometic toilet while sitting on it as you just have to push the pedal with your foot.

Sometimes you may find that your toilet pedal isn’t working while you’re using it. When this happens, the flush on your toilet will stop working as well. It’s usually just some debris stuck in it that is causing the pedal to get stuck. It is easily fixed by cleaning it. Then you will have to take a closer look at the issue if it is still not working.

There’s a good chance your valve and pedal are no longer connected. While most of the repairs are easy for anyone to do on their own, it is still important to be aware of them. There is a spring that connects the foot pedal to the valve. The spring sometimes breaks or becomes loose which causes this problem.

An RV store near you or online can help you buy a new spring. In order to fix your issue, replace the new parts with the broken ones once you receive them. Please be careful not to screw in the screws too tightly, as that will also lead to problems.

2. Leaking Foot Pedal

Leaking Foot Pedal

Sometimes these toilets start leaking at the foot pedal which possibly can be due to the broken or damaged intake valve. Debris buildup or residue around the assembly of the pedal can also be the reason for this leakage. If leaking of the foot pedal is due to debris buildup, it can be resolved by proper cleaning.

A damaged water valve can also cause leakage of the pedal foot. The most common reason for a damaged water valve is improper winterization if the valve is made up of plastic. On the other hand, metal water valves can be damaged by rust.

Sometimes the problem is with the plastic clips that hold the water valve at its connection with the Dometic toilet. Make sure you completely know where the problem is before you start looking for solutions. Most of the time it’s better to completely replace the foot pedal and valve.

3. Water Leaking Out Of Toilet

Water Leaking Out Of Toilet

It is also common to experience a problem in which water starts to drip out of your toilet when you flush. The leaky water can damage your RV if you don’t fix it as soon as possible. Opening up your system is the easiest way to remove this problem.

Upon closer inspection, you will discover that the inlet pipes of your toilet have become clogged. This can be resolved by cleaning out the debris. Alternatively, you can remove the valve and replace it with a new one to enhance the performance of your toilet. Your water should stop leaking after you remove all the debris.

If there is water dripping from the base of your toilet system, this is a totally different issue. This can be resolved by purchasing a new seal. Local markets are an easy place to purchase a new seal.

4. Black Tank Issue

RV users need to remember that the water needs to be loaded into their black tanks before using the toilet. Do not forget to place a few gallons of water. If you don’t do that, your solids will drop off and end up on the bottom of your black tank. Floating up solids and then removing them is not possible with flush water. The result is that they will all get stuck to the bottom of the tank and start to pile up.

You’ll have an even bigger problem if you leave the water valve open to prevent this. There will be a lot of water wasted while the solids will get stuck straight down into the tank. After the tank has been filled, it will prevent the tank from filling up with water. There will be only a small amount of water collected and the flush will stop working.

If you hire professionals to fix this, it can be extremely expensive. However, you can fix the problem on your own as well. Trying to do so will take lots of patience and time. You might need at least a few days to completely clean up the tank. To avoid running into this issue, it is better to look out for it before you run into it.

How To Avoid Dometic 310 Toilet Problems?

Every toilet faces problems. From time to time your Dometic 310 toilet may face problems such as broken pedal, water leakage, the seal may not close completely, and many more. For example, if the basin of your toilet remains partially full and never gets empty. There can be a lot of reasons for this including improper flushing. You should know why a toilet malfunctions and what things you can flush down the toilet and what not.

First and the most important thing is to know that you can not flush paper towels, vegetable remains, and other things that can cause blockage. Secondly, you can avoid serious problems from happening if you keep an eye on the very first sign of a clog formation.

Along with checking clog formation and debris buildup, you should keep on checking for any cracks on your toilet seat and its components. Any crack if left unnoticed can cause serious leakage problems and even can result in breaking the whole toilet. Regular inspection of your Dometic 310 toilet is also very important to make sure everything is fine.
